so furious

I am a very unhappy client..... i entered Harris today to have watch batteries replaced at Tokai branch. I have used this store before but after today i will no longer be going back as i took in a perfectly good watch n left with a watch with numbers that have come off n was told it could be fixed at a cost but why should i be fixing it when i handed a perfect watch in. The assistant wasn't even apologetic at all. I am furious ?
